Iindaba

I-rebar ye-fiberglass,kwaziwa njengeI-GFRP (iGlass Fiber Reinforced Polymer) rebar,yindlela esebenza kakhulu endaweni yokuqinisa intsimbi yendabuko esetyenziswa ekwakheni. Inika iingenelo ezininzi, kubandakanya ukumelana nokugqwala, umlinganiselo ophezulu wamandla ukuya kobunzima, kunye nokungaqhubi kombane, okwenza ukuba ifaneleke ngakumbi ukusetyenziswa kwiindawo ezinzima kunye nezakhiwo ezifuna ubomi obude benkonzo. Inkqubo yokuvelisa yokujikaukuhambahamba ngefayibha yeglasiukungenai-rebar yefayibha yeglasikubandakanya amanyathelo aliqela aphambili, ukusuka ekukhetheniukuhambahamba ngefayibha yeglasiukuya kutsho ekuvelisweni kokugqibela kwe-rebar ngokwayo.

Inkqubo yemveliso iqala ngokukhethwaukuhambahamba ngefayibha yeglasi,oluyingqokelela yeengcingo zeglasi eziqhubekayo. Ukukhetha ukuzulazula kubalulekile ekumiseleni iimpawu zokugqibelai-rebar yefayibha yeglasiIglasi ye-E, eyi-formulation yeglasi engena-alkali, isetyenziswa kakhulu ekwenzenii-rebar yefayibha yeglasingenxa yokuhambelana kwayo nee-polymer matrices kunye nokukwazi kwayo ukubonelela ngamandla aphezulu kunye nokuqina. I-E-glass roving, ene-filaments efanayo neqhubekayo, iba yinto ephambili ekrwada yenkqubo yokwenziwa.

Xa sele ifanelekileukuhambahamba ngefayibha yeglasiikhethiwe, idlula kuthotho lwamanqanaba okucubungula ukuze iguqulwe ibei-rebar yefayibha yeglasi.

Inkqubo yemveliso idla ngokubandakanya la manyathelo alandelayo:

Ukulungiswa Kokuzulazula: Ukuzulazula kwefayibha yeglasi kuyahlolwa, kucocwe, kwaye kugqunywe ngezinto zokulinganisa, nto leyo ephucula ukunamathelana phakathi kwefayibha yeglasi kunye ne-polymer matrix eya kuthi kamva ivale i-rebar. Ukulinganisa kwakhona kunceda ukukhuselaimicu yeglasiekukrazuleni nasekuphathweni ngexesha lokucubungula okulandelayo.

Ukuhlanganiswa kunye noKwakhiwa: Imicu emininzi yeiglasi egqunywe ngefayibha ehambahambayoZihlanganiswa zize zitsalwe ngebhafu yeresin ukuze zifakwe iresin yepolymer, ngesiqhelo ipolyester okanyei-vinyl esterEmva koko iirovings ezifakwe ngaphakathi zitsalwa ngedayi yokubumba ukuze zenze ububanzi kunye nemilo efunekayo ye-rebar.

Ukunyanga kunye nokuqinisa: Okubunjiweyoi-rebar yefayibha yeglasiemva koko ifakwa kwinkqubo yokunyibilikisa, apho i-resin ye-polymer ifumana i-chemical reaction ukuze iqine kwaye idibane neefayibha zeglasi, nto leyo ephumela kwi-composite material eqinileyo nehlala ixesha elide.

Ukusika kunye nokuPakisha: Emva kwenkqubo yokunyanga,i-rebar yefayibha yeglasiinqunyulwe ngokobude obufunekayo kwaye ipakishwe ukuze isasazwe kwiindawo zokwakha nakubavelisi ukuze isetyenziswe kwizicelo zokuqinisa ikhonkrithi.

Iingenelo ze-fiberglass rebar

Iingenelo zei-rebar yefayibha yeglasingaphezu kokuqinisa intsimbi yendabuko zininzi kwaye zibalulekile. Okokuqala,i-rebar yefayibha yeglasiinika ukumelana nokugqwala okugqwesileyo, nto leyo eyenza ukuba ifaneleke kakhulu kwiindawo apho i-rebar yentsimbi iya kuwohloka ngokuhamba kwexesha, njengezakhiwo zaselwandle, izixhobo zokucubungula iikhemikhali, kunye neziseko ezikwiindawo eziselunxwemeni. Iimpawu zayo ezingahambisi umbane ziyenza ifaneleke ukusetyenziswa kwiindawo ezinombane kunye ne-MRI.

Ngaphezu koko,iibha zefiberglassUmlinganiselo ophezulu wamandla ukuya kobunzima wenza kube lula ukuphatha nokufakela, kunciphisa umsebenzi kunye nexesha elifunekayo kwiiprojekthi zokwakha. Ubunzima bayo buyenza ifaneleke kakhulu kwizicelo apho ukunciphisa ubunzima besakhiwo siphela kuyingxaki, njengakwiibridge decks kunye nokulungiswa kwe-seismic.

Ukongeza kwiimpawu zayo ezibonakalayo,i-rebar yefayibha yeglasiInika ubomi obude benkonzo kunye neemfuno ezincinci zolondolozo, inegalelo ekuqineni nasekuzinzeni kwezakhiwo zekhonkrithi eziqinisiweyo. Ikwabonelela ngokuguquguquka koyilo, ivumela ukwenziwa ngcono kwezicwangciso zokuqinisa kunye nokuphunyezwa kwezisombululo ezintsha zokwakha kunye nobunjineli.

Ngamafutshane, inkqubo yemveliso yokuguqulaukuhambahamba ngefayibha yeglasiukungenai-rebar yefayibha yeglasikubandakanya ukukhetha ngononophelo nokulungiselela izinto ezikrwada, kunye nokuhlanganiswa ngokuchanekileyo, ukufunxwa, kunye neenkqubo zokunyanga.i-rebar yefayibha yeglasiInika iingenelo ezininzi ngaphezu kokuqinisa intsimbi yendabuko, kubandakanya ukumelana nokugqwala, umlinganiselo ophezulu wamandla ukuya kobunzima, ukungaqhubi kakuhle, kunye nokuqina ixesha elide, okwenza ukuba ibe yenye indlela enomtsalane kwiintlobo ngeentlobo zezicelo zokwakha.
